Fix input focus flow in profile dialog

[Himanth-reddy]

This pull request enhances the user experience of the profile dialogs by improving keyboard handling and focus management, especially when interacting with text inputs and dialog buttons. The main focus is on ensuring that the soft keyboard is shown or hidden at appropriate times, auto-focusing the name input when adding a profile, and providing consistent behavior across touch and non-touch devices.

Keyboard and Focus Management Improvements:

• Introduced showKeyboard and hideKeyboard helper functions to control the soft keyboard visibility more reliably when focusing or dismissing the name input field. These functions are now used throughout the dialog for better consistency. [1] [2] [3] [4]
• Updated the logic so that the keyboard is automatically shown and the name input is focused when adding a new profile (autoFocusNameInput = true), but not when editing an existing profile. [1] [2] [3]
• Improved the handling of the "Done" action and Enter key in the name input: the keyboard is now hidden and focus is moved to the confirm button when either is pressed, improving usability on both touch and non-touch devices.

Dialog Button Behavior:

• Ensured that the keyboard is hidden before executing any dialog button action (Confirm, Cancel, Delete), preventing the keyboard from lingering after the dialog is dismissed or an action is taken. [1] [2]

Other UI/UX Enhancements:

• Added .focusable() modifier to dialog buttons on touch devices to improve accessibility and focus handling.
• Minor import addition for KeyEvent to support improved keyboard handling.
